Examples for .NET (NuGet package)

Set the license key

HolidaySystem.LicenseKey = "TheLicenseKey";

Check the license

var licenseKey = "TheLicenseKey";
var licenseInfo = Nager.Date.License.LicenseHelper.CheckLicenseKey(licenseKey);
if (licenseInfo is null)
{
    //license key invalid
    return;
}

if (licenseInfo.ValidUntil < DateTime.Today)
{
    //license key expired
    return;
}

Get all holidays of a country and year

var holidays = HolidaySystem.GetHolidays(2024, "DE");
foreach (var holiday in holidays)
{
    //holiday...
    //holiday.Date -> The date
    //holiday.ObservedDate -> The date on which the holiday is observed
    //holiday.LocalName -> The local name
    //holiday.EnglishName -> The english name
    //holiday.NationalHoliday -> Is this public holiday in every county (federal state)
    //holiday.SubdivisionCodes -> Is the public holiday only valid for a special county ISO-3166-2 - Federal states
    //holiday.HolidayTypes -> Public, Bank, School, Authorities, Optional, Observance
}

Get all holidays for a date range

var startDate = new DateTime(2016, 5, 1);
var endDate = new DateTime(2024, 5, 31);
var holidays = HolidaySystem.GetHolidays(startDate, endDate, CountryCode.DE);
foreach (var holiday in holidays)
{
	//holiday...
}

Check if a date is a public holiday

var date = new DateTime(2024, 1, 1);
if (HolidaySystem.IsPublicHoliday(date, CountryCode.DE))
{
    Console.WriteLine("Is a public holiday");
}

Checks if the given date falls on a weekend day

if (WeekendSystem.IsWeekend(date, CountryCode.DE))
{
    Console.WriteLine("The date is in the weekend");
}
